Package io.deephaven.plot.axistransformations

Class AxisTransformBusinessCalendar

java.lang.Object
io.deephaven.plot.axistransformations.AxisTransformBusinessCalendar
All Implemented Interfaces:
AxisTransform, Serializable
public class AxisTransformBusinessCalendar extends Object implements AxisTransform, Serializable
AxisTransform into business time. Useful for plotting time series data with large gaps in non-business hours.

The forward transform takes a data value from standard epoch time and translates it into the cumulative business time for the dataset. The inverse transform takes it back to standard epoch time.

Data values outside of business hours are not visible.
